ANAGERS
Use the Administration > SNMP (Configure Trap) page to specify the host
devices to be sent traps and the types of traps to send. Traps indicating
status changes are issued by the switch to the specified trap managers.
You must specify trap managers so that key events are reported by this
switch to your management station (using network management
software). You can specify up to five management stations that will receive
authentication failure messages and other trap messages from the switch.

Notifications are issued by the switch as trap messages by default. The
◆
recipient of a trap message does not send a response to the switch.
Traps are therefore not as reliable as inform messages, which include a
request for acknowledgement of receipt. Informs can be used to ensure
that critical information is received by the host. However, note that
informs consume more system resources because they must be kept in
memory until a response is received. Informs also add to network
traffic. You should consider these effects when deciding whether to
issue notifications as traps or informs.
To send an inform to a SNMPv2c host, complete these steps:
Enable the SNMP agent
1.
Create a view with the required notification messages
2.
Configure the group (matching the community string specified on

the Configure Trap - Add page) to include the required notify view
(page 379).
Enable trap informs as described in the following pages.
4.
To send an inform to a SNMPv3 host, complete these steps:
Enable the SNMP agent
1.
Create a local SNMPv3 user to use in the message exchange
2.
process (page 385). If the user specified in the trap configuration
page does not exist, an SNMPv3 group will be automatically created
using the name of the specified local user, and default settings for
the read, write, and notify view.
